Evolve more to adapt better: the promise of Arabidopsis thaliana

For plants, adaptation means having the ability to evolve their genome. With the rapid changes in their environments, plants are struggling to keep up with this frantic pace: the rapid evolution of genes is, therefore, a major challenge. In a study notably conducted by the LGDP (UMR CNRS/UPVD), researchers have shown the possibility of accelerating the duplication of chromosome portions, which promotes the evolution and adaptability of plants.

Published in the journal Genome Research, the study conducted on a line of the Arabidopsis thaliana plant goes even further, as presented by the CNRS in an article entitled "Dupliquer pour s'adapter ou comment accélérer l'évolution des plantes..." ("Duplicating to adapt or how to accelerate plant evolution...") and published online in October. Read the article (French)
